Abamectin is also known as Avermectin B1a. Trade names include Affirm, Agri-Mek, Avermectin, Avid, MK 936, Vertimec, and Zephyr.
Introduction
Abamectin is used to control insect and mite pests of a range of agronomic, fruit, vegetable and ornamental crops, and Abamectin is used by homeowners for control of fire ants. Abamectin is also used as a veterinary antihelmintic.
Abamectin is a mixture of avermectins containing > 80% avermectin B1a and < 20% avermectin B1b (1). These two components, B1a and B1b have very similar biological and toxicological properties. The avermectins are insecticidal or anthelmintic compounds derived from the soil bacterium Streptomyces avermitilis. Abamectin is a natural fermentation product of this bacterium. Abamectin is used to control insect and mite pests of a range of agronomic, fruit, vegetable and ornamental crops, and Abamectin is used by homeowners for control of fire ants. Doses of 50 to 200 ug/kg of ivermectin, a similar member of the avermectin family of comounds, is widely used to treat humans in the World Health Organization onchocerciasis (river blindness) program.
Mode of Action:
Abamectin attacks the nerve system of insects and mites, causing paralysis within hours. The paralysis can not be reversed. Abamectin is active once eaten (stomach poison) although there is some contact activity. Maximum mortality occurs in 3-4 days.
Applications:
Mode of action Insecticide and acaricide with contact and stomach action. Has limited plant systemic activity, but exhibits translaminar movement. Uses Control of motile stages of mites, leaf miners, suckers, Colorado beetles, etc. on ornamentals, cotton, citrus fruit, pome fruit, nut crops, vegetables, potatoes, and other crops. Application rates are 5.6 to 28 g/ha for mite control, 11 to 22 g/ha for control of leaf miners. Also used for control of fire ants. Phytotoxicity May be phytotoxic to pome fruit when mixed with captan.
Target: Plant:
Greenhouse-, Shadehouse-, and Field-Grown Ornamentals, Foliage Plants, Christmas Trees, and other Woody Ornamentals
Pest:
Mites: European Red Mite, Two-spotted Spider Mite, Carmine Spider Mite, Southern Red Mite, Spruce Spider Mite
Tarsonemid Mites: Cyclamen & Broad Mites
Eriophyid Mites: Rust and Bud Mites
Boxwood Leafminer
Liriomyza Leafminers
Aphids, Thrips, Whitefiles
Application Timing:
For optimum control, apply Abamectin when the leaves are young to allow better absorption into leaf tissue. This will extend the residual control period. As leaves age and harden off they lose the ability to take up Abamectin and residual control is greatly reduced.
